Thanks for providing more information.
Well as you describe in my opinion,you need to be seen by an Orthopedist for a clinical examination and undergo MRI of Lumbosacral spine & pelvis to rule out Herniated disc,Nerve compression,Arthritis, which result in sharp pain in hip and leg.
You shouldn't ignore it as such as your symptoms'll gradually get worse over the time.
You may require further prescribed medications like Strong opoid,Gabapentin.
Physical therapy can be effective in your case.
You may require a proper treatment rather than wait & watch approach.
